[DeTomaso] Lean condition and O2 sensors(was fuel pump)

[charles buthala]

I did this to my exhaust system.  
  Bungs are cheep $1
  O2 sensors are about 25 to $30 each
  I wired them to two jacks in the glove box so that I could hook up a hand held voltage meter.  There is a switch to go from cylinders 1-4 and 5-8.  It would be nice to have a circuit to even out the signal, but it does work.  An analog meter would be better, it evens out the signal some due to mechanical lag.

with a selector.
The hookup can be temporary or permanent. This will give a 
real-time reading
of rich/lean on both banks of the V-8, well before any loss of 
metal occurs. "


Since my current engine rebuild is taking a bit longer than 
planned and the headers are off of the engine and car and your 
"best/simplest/cheapest way" outlined above is attractive and interesting, 
then.......

What would be the budget to obtain and install the above 
system? Sources and vendors?


Curious, Chuck Engles
